Sir, I hear you had a problem with your RS232 and fixed it. Let me know if this is not right and I will send you a RS232 troubleshooting guide that will nail down the problem for you. The second issue I hear you speak about is the axis alarms. You say you have checked the low voltage power supply and have a good +-12 VDC. What is really important is your 5VDC. It must be between 5.1 and 4.9 or you will start to have trouble like you are seeing. I would also check the ground to your machine and make sure it is solidly grounded. One last task I would recommend is to remove each of your controller cards, clean the gold tabs with scotch brite, brush them off and reinstall them. Make sure they seat firmly and connected back up the bullet connectors that you pulled off. Make sure they are tight in their receivers. Power up and see what you come up with. Let me know what you are seeing after completing my suggestions.
